# Mirror github.com/alchaincyf/nuwa-skill (MIT) into Moments private Gitea.
#
# Why we mirror: Atlas's claw-boss-distiller depends on nuwa-skill methodology
# (`references/extraction-framework.md`). For air-gapped client deployments where
# the client network cannot reach github.com, our private Gitea must serve nuwa.
#
# Prereq: a destination repo on git.moments.top must already exist (empty).
# Default target: https://git.moments.top/Moments.top/nuwa-skill.git
#
# Create it once via Gitea UI (the bot account doesn't have org-create scope):
#   https://git.moments.top/repo/create  →  owner: Moments.top  →  name: nuwa-skill  →  empty
#
# Usage:
#   ./scripts/mirror-nuwa-to-moments.sh
#   ./scripts/mirror-nuwa-to-moments.sh https://git.moments.top/your-org/nuwa-skill.git
#
# After first mirror, schedule a weekly cron to re-mirror upstream changes.
